No, it is not enough to raise money, but with 100$ you can try exchanges and even try leverage (margin trading)
I can't avoid trading and even when I don't have enough money , I still use small amount for trading
$ 100 for me is enough to learn trading with the reason you are really new to trading. start reading the market tred patiently, thoroughly and precisely because it's the key to success in making profits and keep yourself away from emotion and greed because loss starts from it all
